STEAM AND WATER BOILER.

Application filed April- 30, 1919; Serial No. 293,777.

To cZZ'wlw'm it may concern: 7

Be it known that I, CHRISTIAN VF. BACH- LER, a citizen of the United States, residing in the city andcounty of Philadelphia, State of Pennsylvania, have invented a new and useful Steam and lVater Boiler, of which the following is a specification.

My invention consists of a novel construction of a steam and water boiler embodying a water jacket, a series of U-shaped water-receiving tubes in the body ,of the boiler communicating with said jacket, a' central fuel magazine, a fuel inlet in the dome of said body, a fuel directing chute connected with said dome and extending inclined from said inlet to said magazine, means for connecting said chute with said 'magazine, a closure for said magazine mounted'on the top thereof, and a baflie plate in the body around the-upper. end of said magazine connected therewith, said tubes being below said baflie plate whereby the heat acts on the vertical portions of-said tubes and the lateral bends thereof before escaping into the dome,;while the central magazine issupported in ,the body by a collar on said fuel chute, said magazine supporting also the closure therefor and the baffle plate.

To the above ends my invention consists of a novel construction of asteam and water boiler wherein the maximum available space within the water jacket is occupied by water tubes collocated in a novel manner which are efficiently subjected to the-products of combustion, said boiler being adapted to be used as a magazine feed or as a base burner, provision being further 'made for any of the boiler tubes to be readily accessible according to requirements, at all times v :for :the purpose of inspection, replacement orrepair. I I I v.

For the purpose of illustrating y ini vention,-I have shown in the accompanying drawings one form-thereof which is at present preferred byine, since the same will be found to give satisfactory and reliableresults, althoughit is'to be understood that the various instrumentalities of which my inventionconsistsrcan be variously arranged and organized and that my invention isnot limited to the precise arrangementv and organization of these instrumentalities as herein shown and described.

Figure 1 represents a vertical; sectional view of a steam and Water boiler embodying my invention, the section being taken on the line 1-1 Figure 2. 1 I

Figure 2- representsa transverse section on line 22 Figure 1. 7 w Similar numerals of reference indicate correspondingv parts in; the figures,

Referring to the drawings.

1 designates the body of steam and water boiler, the same having a base 2 of any suitable construction, which carries the grate 3 of any conventional type On the base 2 is supported the annularwater acket A, which compr ses the outer shell 5 and the inner shell 6, said shells being suitably supported upon the annular base flange 7, and secured thereto by rivets, bolts or other fastening devices 8. The-upper portion ofthe water jacket formed by the shells 5 and 6 is closed by the upper ring 9, which is secured to the shells 5 and 6 by the fastening bolts 10 which pass through said shells and ring and so is firmly held in position. Upon the upper portion of said ring or water jacket, I 10- cate the dome 11,which is secured in place by the stud bolts 12 which may .be two or the removal of the nuts from the bolts 12 the dome can be readily lifted from the top of the boiler for the purpose of obtaining ac cess to the interior. The upper portion of the dome is provided with a neck or chamber 13, having the door 14 leading thereinto, aid chamber having a flue or outlet 15 for the exit of the products of combustion.

16 designates a door leading to" the chute 17, which communicates with the central magazine 18, which is closed .by'the door 19 which can be actuated from the exterior by the-handle 20. The chute 17 whichbegins at the. inlet in the dome 11 extends downwardly from the latter in inclined direction 7 to the top of the magazine where its lower endLis provided with a collar 17?" which enla circles said top and is secured thereto by bolts or other suitable means, thus firmly sustain 'ingfthe chute in position,

It will be seentalso that the central magaconnection of the door 19 and the bafiie plate 31. p

21 and 26 designate a series of circulating or U tubes which are expanded at their upper and lower ends 22 and 23 into said inner shell 6, it being noted that directly opposite to the ends 22 and 23 of said tubes the plugs or closures 24 and 25 respectively are located in the outer-shell 5, wherebyaccess can be readily had to the end of any desired tube at the outer shell when the respective plugs are removed. 2

It will be apparent that the 'long tJ-shaped tubes 21-project inwardly and extend longitudinally for a great portion of their length in close proximityto the magazine 18, their lower ends 23 entering the water acket: 4 at a point near the lower portion of the combustion chamber '30, while their upper ends 22' enter the inner shell 6' at a point in proximity" to the water line,so that a rapid and effective circulation will be at all times maintainedwithin the boiler.

It will be seen from Figure 2 that when 'the long tubes 21 are in position there is a considerable space or area between them which is ordinarily not utilized, but in my present invention, bythe employment of the intervening shorter-U-tubes 26, I utilize this space or-area so that the long and short tubes 21 and "26 are arranged in staggered -order so as: to-substantially fill the upper portion of the combustion chamber 30 whereby a very considerable tubular area is subjected to the action of the heat units and products of-con'ib-ustion'so that practically the entire area within the water jacket L l is occupiedhy the st 'ered tubes 21' and 26 which are effectively s iibjected to the efiect 6f the products oiro-mbustion.

27'designates a series -of-plugs,-see Figure 2, which are-located in aligi'iment-with the ends of ft'he shorter tubes 26, whereby access can be readily liad' the ends of said'tubes for the purposefo f inspection or repair.

28 designates an opening through the lower'fportion "of thewater "jacket, which is closed by-the door'29, whereby access can-'be had and fuel supplied to the lower portion of the combustion chamber 30,-it being'apparent that my device can consequently be used as a'magazineburner or base burn-er;

81 designates a deflector attached to the upper portion of the magazine 18 and having the= holes 32 thercthrough asa' bailie plate to'cause' theheat'te act directly onthe vertical portions aswell'as the terminal lat- --eral bends of the several U shaped tubes becording to requirements.

'ters-P atent, i's-: p V r 1 in a boiler of the" character stated; a" body having a -'water jacket, a domehaving fore escaping into the'dome,it-being evident.

that said tubes are below said battle plate.

It will be apparent from the foregoing that in my invention, 1 dispense with a crown sheet and thereby'eliminate th'elia bility of explosions since it is well known that a great majority of boiler explosions.

are due to thecollapse ofthe crown sheet,

it willfurther lie-apparent, that a very effective maximum area is sub ected to; the

action of the heat units and products of com the bolts 12 when the dome is disconnected from thering and may then be removed.

By "the employn'ientortlie-magazine 18 as a magazine burneror a base burner, ac- I [While I have denominated tor thepu-rpose of distinction the tubes 26 as short, and the tubes 21' as long, sald tubes '26 areturned than saidj 'tubes 2l,"and so the-former are adapted to occupy the spaces-between the latter, whereby said spaces are utilized to into the heating chamber ma less" eiitent receive said tubes26 with the advantage 4 hereinbeiore stated.

' It will now be apparent that I have devised a novel and useful construction-ofa steam and water boiler which embodies the thep-resent instance, shown-and described a preferred embodime-ntthereofwhich will be found in practiceto give satisfactoryahd reliable re'sult's,-it is to be understood that the same is susceptible-of modification in various particularsv without departing-"from 'the spirlt or scope e f-the invention or -sac rifi'cing any of itsadvantages.

\ Ha-ving'thus described -my'1nvcntion what I claim as new and deslre to secure 'by Leta fuel inlet therein, means forconnecting 7 said dome with said body, aeentralinagazine, a closure for said magazine mounted on the top thereof, means for operating said let to said magazine, a collar on the inner dome of the boiler surrounding said central end of said chute with which said magazine magazine below said baffle plate and comis connected and by which it is sustained in In'unieating with said water jacket.
